Forced deployment sequence

摘要

A fixed sequence activation handle has at least a first (128), second (302) and third removable member (702) each attached to a distally extending line (120, 122,126) in communication with a remotely located deployable device having a first and second portion wherein removal of the first member from the handle results in partial deployment of the first portion of the remotely located deployable device thus allowing access to the second member. The second member can include a rotatable portion (304) wherein rotation of said rotatable portion modulates the first portion of the deployable device and wherein removal of said second member results in complete deployment of the first portion of the device and allows access to the third member. Manipulation of the third member deploys the second portion of the device. The third member is nested within the second member and the second member is nested within the first member.
